Hi Scott,

Changing the stack size should be done in info.plist file. Please access the info.plist file and try.

1. Right-click on JUDE application icon and select [Show Package Contents] from the pop-up menu
2. Go to the Contents folder
3. You'll find the info.plist file,so open it with Property List Editor
4. Open the Java Key, and the VMOptions Key will appear
5. Modify the VMOptions and change the stack size (-Xss)

Hope it works

Best regards,
Satomi
